As a teacher of a second language I've always wondered how I could get more verbal communications out of my students, no matter what the level.
Using their cell phones and the Internet to self-assess instead of engaging in traditional face-to-face conversation with their instructors alleviates students' anxiety and increases their comfort level with the language, helping them learn faster.
Students, meanwhile, should return to their avatars to view instructor comments and replay their recordings; this will help them identify areas in which they are having difficulty so they can work to improve those skills.
